LOOSE-'LEAF BINDER.

' Application., med october so, 1912.. serial no. 728,655.

To all 'whom 'it may concern Be it known that I, JOHN G. Maonuof Rochester, in the county of Monroe and State of New York, have invented a. new and useful Improvement in Loose-Leafl Binders, which improvement is fully set forth in the following specication and .shown in the accom anying drawings.

T e present invention relates to loose leaf binders and more particularly to that type having a removable transfer member. on which certain of the leaves are. held for'the purpose of fitting other leaves to ory removing them from the impaling posts or projections, 'and an object of this invention is to provide a construction in which anV impali-n-g projection and a transfer projection fit within a single opening of each leaf, the projections on the two partsbeing of such a; construction that they are inexpensive4 to. manufacture and coperate with each other in such a manner that they are not liable.

to et out of order. y

o these and other ends the invention consists in certain parts and combinations of parts all of which will be. hereinafter described, the novel features being pointed out in the appended claims.

In the drawings: Figure 1 is a perspective view of a loose leaf binder constructed in accordance with this invention; Fig. 2 is a section through the su porting member, the transfer member and t e retaini member while Ythese parts are -interlocke v; Fig. 3 showsthe transfer member and the supporting member in section and in slightly separated relation; Fig. 4 is a detail sectionall view through one of the im aling and one of .the transfer projections whilethese parte are associated; Fig. 5 is a detail viewof the supporting member showing the impalingprojection in crosssection and the pocket atthe base of the impaling projection; Fig. 6 is an. enlarged detail view of a portion of a; leaf showing one of the post openings; and! Fig. 7 is a detail view showing an opening in the transfer member through'whlch any` im ailing projection passes. f

lli] the illustrated embodiment of the 'ine vention, the binder is in book form, one cover 2 of the book carrying a supporting member and the other cover 8 carrying a re taining member. The supporting.membeI is preferably in the form of a bar 1 incluse within the cover 2 Aand having posts or projections extending laterally therefrom in .parallel relation.v One longitudinal face 3 of each of. these. posts is preferably curved while the. oppositelongitudinal face 4 is flat =so that the post is semicylindrical or has ya cross section of a half of a circle. Like 1 ;longitudinal-faces of these posts -or lprojecgjtlons are opposed, that `1s,inthe-.present instance, the curved facesmon the two. rojectlous are vnext to .each other while t le. flat.,

. the impaling projections, while,at vthe same time, s ace will be provided on the outer .sides o h theposts for thareception 'of trans- ,afer Eroletlone l e transfer projections are at least two .in number and extend. laterallyl inparallel relation from .the transfer member or bar 7. The transferprojections araalso formed, in this embodiment, .with curved 'longitudinal faces 8 and-,'iiatlon tudinal faces .9, the fiat faces of the trans er pro`ections being, in this instance, OPPOSed so t at the curved. faces are onthe out ide or toward theends .of the transfer mem` r.; T he distance be- .tween. the transfer projections 1s greater than the distancebetween the imppling projections; In fact, the distance betweenthe outer fiat faces. ofthe impaling rejections ,corresponds substantially to. the stance between the innerdat faces of the transfer Vprojections so that the transfer pro'ections mayiit snugly within the openings. l ofthe' sheetsat one time withy the impaling projections, theend of the transfer projectlons resting in notc es 10l Ainthe sulppcrting .member 1 at the bases of theimpa ing pro- .ject1ons, and-the latter projecting` throu hL semicircular o nings 1.0 in the, trans er member 7 lat t e bases of the transfer ro- Aieetierls- Whse Se arrensedieach impe ins projection and transfer progection norms a. cylinder::whosediameter` corresponds with the diameter of the opening "in the loose leaf Q1'I Sheet. AIt is apparent @hatch-e leaves or sheets win be held against 'movement on the transfer because the outer curved faces of` the transfer members will engage the outer sides of the two openings in the loose leaves or sheets.

Anys'ut'able means may be emplo ed for holding the transfer 'member an t e supporting member in coperative relation. Preferably, there is employed a retaining member comprising'a tubular casing 12 having a slidin locking bar lor latch 1 3 movable longituf inally therein, and pressed in one direction by a spring 14, mbvement inl the other direction being effected by manipulating the projecting end 15 of the b ar or latch. vIn order that, the latch may `cooperate with `the impaling projections, the latter may be providedl with shoulders 16 rear their upper ends for engagement by the .latch or ar 13, the casing 12 being perforatedat 17 lto permit the entrance of the upper ends of the impaling projections. In the operation o f the invention, assuming the parts to bein the positions shown in Fig. 2 and it is desired to remove a leaf or sheet, the projecting end 15 of the latch le is pressed inwardly to disengage such latch from the shoulders 16 when the binder cover 18 may be thrown backward to the position shown in Fi 1.' The transfer member 7, with a number of leaves or sheets 5 is raised as shown in Fig. 3, after which the desired leaf may be removed without disturbing the position of the leaves onthe paling projections on the supporting member. l ,y 1

4A loose leaf binder constructed in accordance with this invention/requires but two openings in the loose leaves. The transfer projection andthe I impaling-projection may be made `from the same stock and when cooperating form a cylinder which will t "within a 4circular opening.- "The flat cooperating faces on 'the impaling projections and the'transfer projections do not require any expensive tools to form them andthey are not liable to get out of order. The faces also render easy the association of the transfer member with the supporting member.

What I claim as m invention and desire to secure 'by Letters atent is;-

1. A loose leaf binder comprising a sup- 'portingA member'havin a plurality of imlpsiling projections, an a transfer member aving a plurality of transfer rejections,

' the-impahn projections and t e transfer 'projections aying such shapes in cross section that, when one imaling projection is one transfer projection, a complete cylinder is formed, the ends of the impaling projections interlockingwith the transfer member and the ends of the transfer projections with the supporting member to prevent relative lateral movement between the projections.

2. A loose leaf binder comprising a supporting member having a plurality of impaling projections and also having pockets near the bases of said projections a transfer member having a plurality of transfer rojections and also having openings at the bases of the transfer projections for the passage of the impaling projections, the impaling rojections and the transfer projections that, when the impaling projection is in abutting relation with one transfer projecends of the transfer projections resting in the pockets of the supporting member, and a retainin member coperatlng with those portions o 'the imp alin projections passed through the openings o the transfer memer.

3. A loose leaf binder comprising a su porting member having a pair of para el impaling projections, each having a flattened face and a 'curved face, the `opposed faces of the projections being of thel same form, said supporting member also having pockets near t e bases of the impaling projections, and a transfer member provided with a pair of parallel transfer projections, each having a flattened face and 'a curved face, the oppgsed faces of the two transfer projections ing alike but different from the op osed faces of the impaling projections, t ose projections having the fiat faces t ose having the curved faces opposed, so each pair of projections will hold leaves a inst'sidewise movement thereon, the ends o the transfer projections extending into the pockets of the sup orting member.

4. A loose leaf bin er comprising a sulpporting member having a air of aral el impaling projections forme with at 1ongitudina aces, and a transfer member havmg a dpair of arallel transfer rejections forme with at lon 'tudinal aces coperatin with the longltudinal faces of -the impahng projections, the ends of the transfer projections interlocking with the suportmg member and the ends of the impa mg projections interlocking with the transfer member to prevent relative sidewise y'fer member'.
